Coquettish Rebirth

Indeed, in this era, it is really not a problem to make LCD monitors for later generations.Not to mention the ips screen that was popular in 2011 and 2012, even if it is popular in about 10 years, is it the tn color screen?This tn color screen is not as true-colored as a tft screen, and has a little less color scale, so this is one of the places where the later tn screens are not as good as ips screens-the color is poor, and another place that is not as good is the poor viewing angle.

The ips screen can basically reach a viewing range of more than 170 degrees, that is to say, almost from an angle parallel to the screen, you can still see clearly what is displayed on the screen.As for the tn screen, if it exceeds 45 degrees, the visual range will be affected. Even if you look at it from the side, you can only see a reverse white effect, and you can't see what is displayed on the screen at all.But in any case, there are still tn LCD panels in this era.

Although limited by the most economical cutting area, it is not economical to cut a panel of 17 inches or 19 inches or even 20 inches or more, but the small white LED diode has been invented by the Japanese, so now it is really necessary to make LCD at any cost. Screen, it can really be done!And the effect will not be much worse than the LCD screens on the market in 2010!But the problem is that it is not economical!

Historically, LCD panels have always had the most economical cutting size, and this size affects the size of LCD screens that appear on the market!For example.When the manufacturer's n-generation ips screen panel production line, the most economical cutting size is 21.5 inches, then the manufacturer will promote the goodness of the large screen, saying that the 16:9 screen is a real widescreen, which is better than 19 inches, 17 inches, etc. The screen is much better there.This kind of advertisement is actually to lure consumers to buy the most cost-effective 21.5-inch monitor from the manufacturer!When 23 inches is the most economical cutting size, manufacturers will start to say that the dot matrix distance of 21.5 inches is too small, hurting the eyes, or 23 inches with the same 1080p resolution, but with a larger dot matrix distance.

等到了消费者们都买了23寸了，当厂家们的最经济切割比例到了24寸的时候。厂家们肯定又会开始说：16:9的比例是垃圾。最好的是16:10的，16:10的才是真正的宽屏……相信接下去还会有21:9才是真正的宽屏以及48:9才是真正宽屏的言论出现。<真正大行其道的原因。主要还是在于成本。基本上还是要到了0506年的时候。液晶屏才能慢慢的开始代替显示器！

But these are not important.When Jia Hongjian talked about the LCD monitor, he actually wanted to see if this Olsen was a reborn person!If he was a reborn person, then he heard Jia Hongjian mentioning the LCD screen when he knew about it, how would he react?Of course there will be a heroic reaction!But what if he wasn't a reborn?To a large extent, it may be a sudden realization, and then sigh the cost!

At this time, Jia Hongjian looked at Olsen's reaction, and he was 8% sure that Olsen was not a reborn person. If Olsen really won the [-]% chance, he can only be said to be Oscar. A strong candidate for actor!

After sighing at the monitor, Olsen suddenly became much more enthusiastic towards Jia Hongjian!It seems that after mentioning the LCD monitor just now, Olsen suddenly felt that Jia Hongjian was also a fellow!At this time, the pregnant old Ao asked Jia Hongjian with bright eyes, "Hey, boy, take a look at our product and see if there is anything that can be improved?" It turned out that this Ao Sen suddenly had a feeling that when he saw Jia Hongjian first saw the plan, he would be able to realize that such a thin mainframe needs to be matched with an LCD display, so this child seems to have a special ability, at least for this product It seems that he can think of many ideas that Olsen couldn't think of at a glance!So he wanted Jia Hongjian to see if there is any room for improvement in this product!

At this time, I heard Jia Hongjian look at the design drawings and say, "For your product, the main board must not be a product of another company. It must be customized by you. It is estimated to be a small main board less than 17 centimeters? Looking at this height, The heat dissipation problem of the cpu should not be too big. After all, the heat generated by the cpu is not terrible these days. Adding a down-pressure radiator should be enough. Next is the power supply. Looking at this power supply, you should use a direct Plug in the dc-atx power supply? That is, use a small transformer cable like a laptop to reduce space with a bulk power supply? Looking at this series of things, the problem should not be very big. The only possible problem is heat accumulation. After all, there is basically no air duct in such a small space, and it is impossible to use positive or negative pressure to dissipate heat. If the heat accumulates in the chassis, it will not work. However, relying on chips and integrated graphics that do not generate high heat, it is still no problem for office work. questionable……"

Jia Hongjian's comments stunned Olsen, the industry boss!What kind of heat accumulation, what kind of air duct, what kind of positive and negative pressure, he has never heard of it!After all, this is the 90s, where is the cpu of Pentium 5 that the chips of i7 and i955 are so hot, and there is no such thing as amd's Phenom [-] that is so hot!Therefore, there are no tower radiators on the market, and chassis manufacturers have not begun to study how the chassis dissipate heat!

Air ducts and other things, people will only consider it when tower cases become popular in the industry, and then the heat cannot be dissipated!When the cpu frequency has not reached 1g, there is no problem at all with a horizontal chassis. What about air ducts and heat dissipation?

"Oh my god, kid, do you speak English? Why can't I understand the nouns you just said?" Although the old man Olsen was confused, he was still in a humorous mood, and took the nouns he didn't understand as Jia Hung-chien did not speak English as a result.

"Oh, what should I listen to first? Heat accumulation? To put it simply, in a case, after the CPU and other South Bridge and North Bridge chips heat up, the heat will slowly spread out, but there must be places in the case where the air does not circulate, so It seems that hot air may accumulate in this place, and then it will cause heat to accumulate there, and finally affect the temperature of the entire chassis. For example, the top of the chassis you designed does not have ventilation holes, but there is a row of pencil-wide holes on the side. If we don’t use the down-pressure radiator, the heat may accumulate on the top of the chassis and cannot be dissipated, which may eventually lead to excessive heat, the machine restarts or directly shuts down due to overheating…”

After talking about this, Jia Hongjian found that the old man didn't quite understand the other terms, so he simply explained, "The air duct is to use the position of the fan and the position of the cooling holes to design a cooling fan in the case." The inflow channel allows the cold air to pass through the cpu and other chips to absorb heat, and then is exhausted by the fan. It is not a problem for a good air channel to lower the temperature of the entire machine by ten degrees, or even more. .”

After hearing this, Olsen said that he almost understood, "Then what do positive pressure and negative pressure heat dissipation mean?" Jia Hongjian thought for a while, organized his English, and then explained, "The so-called positive pressure heat dissipation , that is to say, there are more suction fans in the chassis than exhaust fans! In this way, more air enters the machine than it exits, and the entire machine will maintain an air pressure slightly higher than the external atmospheric pressure, that is, The so-called positive pressure. As a result, the air in the case, including hot air, will try to find a place to escape. If a cooling hole is opened in a suitable position, the hot air will be relatively high. This way, the whole machine is easier to keep cool. Of course, there is another problem with this kind of machine, that is, the inside of the machine must be relatively sealed, so that the excess air can escape where you want.”

"As for negative pressure cooling, it is the cooling mode of the chassis designed by PC manufacturers these days. Generally speaking, there is no intake fan, only the exhaust fan, or in other words, the incoming air is less than the outgoing air. In this way, The air pressure inside the overall chassis will decrease, and it will become a negative pressure, and it will do everything possible to inhale air from the surroundings into the chassis. The surrounding air must be cold air relative to the chassis, so it is sucked in and cooled. But this brings There is a problem, that is, because the cold air enters from various corners, it will bring a lot of dust to the corners. It can be said that from the perspective of dust prevention, positive pressure heat dissipation is better than negative pressure heat dissipation..."

Jia Hongjian's science popularization really surprised Olsen!The old man really didn't expect that there are so many details inside the broken case!And the kid in front of him knows so much!Of course he would not have guessed that these things are all later generations. After entering the 21st century, DIY became more and more popular in China, and then the heat of the machine became more and more abnormal. Finally, the machine with poor air duct and poor heat dissipation should be used well. When the cpu and graphics card are used, the temperature may rise to 80 degrees, 90 degrees or even 100 degrees when playing nb games!Under such circumstances, how could Jia Hongjian not consider heat dissipation?

Not much to say about this kind of primary air cooling, there are many types of heat dissipation that Jia Hongjian has played with in later generations!He has tried water cooling and oil cooling before!When playing with oil cooling, I spent 5000 yuan to buy a very stable and non-conductive simethicone to soak the entire motherboard, cpu, graphics card, etc., in order to directly surround and dissipate heat!
